Check the Unit

Start with three task durations: Setup is 12, Clean is 18, and Check is 15. The x-axis label says task. The y-axis label says minutes. So the tallest bar reads as 18 minutes. It does not read as 18 dollars, 18 visits, or a unit-free value.

A tiny chart-reading step: check the axis labels and unit before reading plotted values.
